Hello Everyone. I am a beginner at J2EE so this question might be

silly for you but please be kind and help me out. Here is the

problem:

There are 3 buttons "ADD", "UPDATET" & "DELETE" respectively on

a HTML page and 3 TextFields to accept values. The problem is to

accept values from the user and depending on the button clicked

any of the three operations are carried out.if i click ADD button a row is to be added to the db ,if i click UPDATE button a row is to be modified to the db,if i click DELETE button a row is to be deleted to the db

I want to use a servlet to do this. In Core Java we have

ActionListener to listen for events and then depending on the

ActionEvent object's 'trapped' event the suitable processing is

done.

Assign the buttons a name and find out using HttpServletRequest#getParameter() which button was clicked (when the value is not null).

hi,

write the html code like this.

<form action="/cri/test" method="POST">

<input type="submit" name="btn" value="Add"/>

<input type="submit" name="btn" value="Update"/>

<input type="submit" name="btn" value="Delete"/>

</form>

action = /cri/test --> iT's u'r servlet name

Your servlet will look like this,

String s = request.getParameter("btn");

if(s.equals("Add")) {

// insert Code

}

else if(s.equals("Update")) {

// update code

}

else {

// delete code

}

i think this code snippet will help u to complete your application.
